    1,3,4-oxadiazole
    Opis:
    In this study, we report the synthesis of 2,5-substituted 1,3,4-oxadiazole derivatives using condensation of cyclohexanecarbohydrazide derivatives and carbon disulfide. In present study, we have prepared total seven derivatives based on 1,3,4-oxadiazole core further functionalized with thiol moieties. The structures of synthesized compounds (C1-C9) were confirmed by the 1H NMR, and Mass spectrometry. These synthesized molecules were subjected to antibacterial and fungal activity against selected microbial and fungal strains. Some of derivatives showed good biological behaviour against gram positive and gram negative bacteria.

    Opis:
    A novel series of Sulfonamide embedded heterocyclic derivatives were synthesized and well characterized by using 1H NMR, 13C NMR and IR spectroscopic techniques. All the new synthesized compounds were evaluated to their anti-bacterial, anti-fungal and anti- malarial activities. Noticeably, compound 5b was the most potent compound in vitro anti-microbial (S. aureus) with a MTCC value of 96 microgram/ml and compounds 5g and 5j showed most potent activity in vitro anti-fungal (C. albicans) with a MTCC value of 277microgram/ml. Similarly, compound 5e showed high potent activity of anti-malarial (P. falciparum) with mean IC50 value as compared to other synthesized derivatives.

    Various aromatic aldehydes condense with aryl ketone (N-(4-(phenylsulfonamido)phenyl) acetamide) in presence of aqueous alkaline NaOH to form α, β-unsaturated ketone (N-(4-(N-phenylsulfamoyl)phenyl)cinnamamide derivatives or sulfonamide chalcone derivatives). We were synthesized novel sulfonamides chalcones synthesized through Claisen-Schmidt condensation of aromatic aldehydes and sulfonamide containing acetanilide. All the synthesized compounds were characterized using Mass, FTIR, NMR (1H & 13C) spectra analysis. The synthesized sulfonamide chalcone hybrids were screened antimicrobial activity, antifungal and antimalarial activity.

    Opis:
    Artificial neural network (ANN), a Computational tool that is frequently applied in the modeling and simulation of manufacturing processes. The emerging forming technique of sheet metal which is typically called single point incremental forming (SPIF) comes into the map and the research interest towards its technological parameters. The surface quality of the end product is a major issue in SPIF, which is more critical with the hard metals. The part of the brass metal is demanded in many industrial uses because of its high load-carrying capacity and its wear resistance property. Considering the industrial interest and demand of the brass metal products, the present study is done with the SPIF experiment on calamine brass Cu67Zn33 followed by an ANN analysis for predicting the absolute surface roughness. The modeling result shows a close agreement with the measured data. The minimum and maximum errors are found in experiment 3 and experiment 7 respectively. The error of predicted roughness is found in the range of –30.87 to 20.23 and the overall coefficient of performance of ANN modeling is 0.947 which is quite acceptable.

    Opis:
    A novel series of chalconyl vinyl ester based derivatives were designed and synthesized. The newly synthesized compounds were studied for efficacy against several bacteria (E.Coli, P.Aeruginosa, S.Aureus, S.Pyogenus) and fungi (C.Albicans, A.Niger, Clavatus) using the broth dilution technique. Chalcones were prepared by treatment of 4-iodo acetophenone with 4-hydroxy benzaldehyde by Claisen-Schimidt condensation reaction. Various chalconyl vinyl ester derivatives (C1-C8) were prepared by reaction of chalcone with 4-n-alkoxy cinnamic acids derivatives. Compound C8 shows the best bioactive desired antibacterial analogue with less MIC value against different tested strains. All the final synthesized compounds were characterized by IR, 1H NMR, and elemental analysis.
